This high-performance BS 6231 600/1000V PVC insulated,non-sheathed flexible cable is designed for 600/1000V applications and manufactured according to BS TYPE BK / TYPE CK standards. It is mainly used for the internal wiring of switchboards, control panels, metering units, relay cabinets, and instrument panels of power switchgear. It is also suitable for internal connections within rectifier systems, motor starters, and controllers. Constructed with stranded copper conductors and high-grade PVC insulation, the cable offers mechanical flexibility, flame retardance, and excellent electrical performance in compact control and automation environments.
Basic design to to BS 6231: 2006
